    May I add Computer Graphics From Scratch, which covers both rasterization and raytracing? https://gabrielgambetta.com/computer-graphics-from-scratch/i... I have to admit I'm quite surprised by how eerily similar this website feels to my book. The chapter structure, the sequencing of the concepts, the examples and diagrams, even the "why" section (mine https://gabrielgambetta.com/computer-graphics-from-scratch/0... -…
